Hello Everyone,

 

Just got my set of braces from Mine's via EMS today. They look simple and well made. Knowing Mine's I'm assuming there will be some tangible result (at least in feel). Pics below.

 

I'll report back when I get them installed.

cool!

 

a mechanic noticed as he opened doors on some 09's that they would be hard to close and not align due to flex in the body, where as newer cars had no flex.

 

Maybe these will help noticeably!

very cool pieces, I regard my 09 GT-R to be the stiffest chassis car I have ever driven, but I guess there is always room for improvement! Knowing Mines I am surprised these are not made out of carbon fiber or titanium.

Wouldn't hold the torsional loads.  Maybe thick titanium or aluminum might, but CF has no hope.

I would have guessed as much, but I still can't figure out why they can make a driveshaft out of carbon fiber, and even in a 1000whp GT-R it still isn't the weak link!

Carbon fiber is only strong when loaded parallel with the weave. I forget the enginerd speak, but there's a term for it. Like Shawn said cf wouldn't hold up to being loaded that way. This is why when I first saw the cf 'strut brace' on factory DBA cars I just laughed... I guess even the boffins at Nissan have a little ricky ricer in them.

You don't the carbon fiber strut brace think it makes a difference?  We're talking Mizuno here, dude!

The secret is round, and the weave.

It does, and I have one, but that one is woven special with a resin, and is subject to very little motion. In the DBA, it is also screwed down every foot or so.

Icarus raises a good point though. And, I know I just "know" that CF wouldn't support the loading on that kind of gusseting. That part will not only see pull, but also push, and twist. Just my experience that CF cannot do all of that.

I remember when one of the F1 cars suspension arms just exploded into dust, and I saw the film. I remember thinking "what made you think they would hold up to that?", but at least it was an unusual occurrence.

the carbon dba brace is just wrapped in carbon for the look.

and the tolerances in the gtr builds as years go on has improved.

mizuno had the workers drive a gtr with loose tolerances and then one with tighter so the workers seen first hand why its important, hence why its improved through the years.

Interesting Ian - I was under the impression that it was actual carbon fiber. I'll have to look more closely at my buddy's DBA car next time he's got the hood up. It's more the shape that makes it weak, VS the material. Wrapping it up and around the builkhead is just going to load it in all the wrong directions. It's like a bow and arrow - you don't design the bow and then expect it not to bend...

 

I was under the impression that most of the DBA's stiffer chassis was due to extra steel bracing around the firewall area which is spot welded onto the chassis before assembly. I saw a diagram of it in a thread on the other forum - I can go try to search for that if people are curious...

I've seen pics of those firewall reinforcements too. They are in very specific areas, I remember thinking they must have some real data telling them it would make a difference.

Be careful that you know that that brace is anchored into the firewall about every 12 inches.  It is screwed pretty handily in, so the end - to - end torsion is basically meaningless on that brace in isolation, it is tying the anchor points to the firewall in another dimension with  an extra brace.

And the bolts gusseting it to the firewall on the brake booster side...

So, it's not just a tower brace, but it reinforces the firewall and connects the top of ths strut tower to it in an upwards dimension.

Ditto - and I had no idea that there were bolts every foot on that CF piece, that would make a big difference... D'oh! gotta look under the skin...

Those are the most beatiful pieces of metal i have ever seen, damn.
